Barcelona striker David Villa has been admitted to hospital with kidney stones, the Primera Division leaders have confirmed.

A club statement said: "The club's medical services have announced that David Villa was admitted to hospital due to a nephritic colic infection. The player will undergo kidney stone treatment in the coming hours.

"At this point, David Villa is doubtful for the match against Granada on Saturday."

The 31-year-old Villa scored in Sunday's 6-1 rout of Getafe, a result which - combined with Atletico Madrid's surprise defeat against Rayo Vallecano - sent Barca 12 points clear at the top of the table.
